.COLDEST TEMPERATURES OF THIS WINTER SEASON TO IMPACT THE AREA
TONIGHT...

DISCUSSION...STRONG COLD FRONT JUST CLEARED THE BIG BEND REGION
AND HAS EYES ON SOUTH FL THIS AFTERNOON. DEWPOINTS BEHIND THE
FRONT ARE IMPRESSIVE...IN THE SINGLE DIGITS WITH TLH REPORTING A
DEWPOINT OF 9F NOW. THE FRONT WILL CLEAR THE PENINSULA LATE THIS
AFTERNOON WITH HIGH PRESSURE OF ARCTIC ORIGIN BUILDING IN FROM THE
NORTH IN ITS WAKE. ALL IS ON TRACK FOR A FREEZE ACROSS MOST OF
THE AREA OVERNIGHT THROUGH EARLY THURSDAY MORNING. GFS GUIDANCE
HAS BEEN FAIRLY CONSISTENT...AND THE NAM HAS EVEN LOWERED. RIGHT
NOW CURRENT EXPECTATIONS ARE FOR A HARD FREEZE ACROSS GLADES,
HENDRY, INTERIOR PALM BEACH, AND INTERIOR COLLIER COUNTIES WITH
TEMPS OF 28F OR LESS FOR 4 OR MORE HRS...SO A HARD FREEZE WARNING
HAS BEEN ISSUED FOR THESE AREAS. A FREEZE WARNING HAS BEEN ISSUED
ACROSS THE REST OF INTERIOR AREAS...AS WELL AS INTO THE GREATER
NAPLES AREA AND THE WEST PALM BEACH METROPOLITAN AREA...BUT
FREEZING TEMPS WILL BE MORE SPOTTY AT THESE LOCALES. HAVE ALSO
INCLUDED METRO BROWARD IN A FREEZE WARNING...AS COMMUNITIES NEAR
THE SAWGRASS EXPRESSWAY AND OKEECHOBEE ROAD COULD BRIEFLY HIT THE
FREEZING MARK. FOR COASTAL BROWARD...METRO AND COASTAL MIAMI-
DADE...THE MOST LIKELY SCENARIO IS FOR TEMPS TO BOTTOM OUT IN THE
MID TO UPPER 30S...SO THEY ARE LEFT OUT OF ANY FREEZE
WARNING...BUT DAY SHIFT WILL ASSESS CURRENT TRENDS TO SEE IF ANY
EXPANSION WILL BE NEEDED.

ASIDE FROM THE FREEZE...WIND CHILLS WILL BE A FACTOR OVERNIGHT.
BUT JUST HOW LOW WIND CHILLS GO WILL ALL DEPEND ON HOW MUCH THE
WINDS STAY UP OVERNIGHT. THIS IS ALWAYS THE MILLION DOLLAR
QUESTION. ALL GUIDANCE...INCLUDING THE NAM AND WRF DEPICT WINDS
EVEN INTERIOR AT 5-10 KT. BUT FROM PREVIOUS COLD EVENTS...WE KNOW
THIS CAN BE WAY OVERDONE. HOWEVER...THERE DOES SEEM TO BE A BETTER
PRESSURE GRADIENT AND LLVL WIND SURGE BEHIND THIS FRONT. AS
SUCH...MIN WIND CHILLS COULD FALL AS LOW AS THE UPPER TEENS ACROSS
THE LAKE OKEECHOBEE REGION TO THE 20S TO AROUND 30 ELSEWHERE. HAVE
ISSUED A WIND CHILL WATCH...DUE TO THE POSSIBILITY OF WIND CHILLS
OF 25F OR LESS FOR 3 HR OR MORE...FOR ALL EXCEPT METRO AND COASTAL
BROWARD AND MIAMI-DADE COUNTIES. FOR THE SE METRO AREAS...WIND
CHILLS OF 25-30 ARE EXPECTED FOR SEVERAL HOURS...WHICH WILL LIKELY
NECESSITATE THE ISSUANCE OF A WIND CHILL ADVISORY LATER TODAY.

HIGHS WILL STRUGGLE TO REACH 60 ON THURSDAY...THEN ANOTHER COLD
NIGHT IS EXPECTED OVER WESTERN INTERIOR AREAS WITH ANOTHER FREEZE
POSSIBLE. BUT TO NOT COMPLICATE MATTERS...DID NOT ISSUE A FREEZE
WATCH AT THIS TIME.

TO MAKE A LONG STORY SHORT - FRIDAY AND INTO THE MIDDLE PART OF
NEXT WEEK WILL FEATURE MODERATING TEMPERATURES ALONG WITH CONTINUED
DRY WEATHER. TEMPS WILL MOVE BACK TO ABOVE NORMAL BY EARLY NEXT
WEEK.

MARINE...RATHER STRONG NW WINDS WILL PREVAIL NEXT SEVERAL DAYS
LEADING TO A CONTINUATION OF HAZARDOUS GULF STREAM SEAS. BRIEF
WIND SURGE EXPECTED ACROSS THE GULF TODAY...SO ISSUES A SCA THERE
AS WELL.

FIRE WEATHER...RED FLAG WARNING EVERYWHERE THIS AFTERNOON/EVENING
AND THURSDAY AS WELL WITH HIGH CONFIDENCE IN RHS TANKING INTO THE
20S THIS AFTERNOON...EXCEPT 30S GULF COAST...AND TEENS AND 20S ON
THURSDAY. NW WINDS WILL PICK UP THIS AFTERNOON AND BE SOMEWHAT
LESS ON THU. RHS WILL MODERATE FRIDAY AND BEYOND.
